Sorry to revive a dead thread, but since I can't seem to find my Peake tool currently I'm going to do the paperclip and pin 7 & 19 to reset my oilservice light on a '95 M3. Will doing this potentially clear any latent codes my car may have that I'm not aware of? I don't have a CEL but have had codes in the past by using the Peake when no light was present at the time of an oil reset. The CEL works, it just isn't illuminated at the moment.
